Kinnikuman Big Body (キン肉マンビッグボディ), originally Strongman, was one of the Five Fated Princes (運命の五王子, Unmei no Go Ouji) from the final story arc of Yudetamago's manga series Kinnikuman.

Kinnikuman (a.k.a. Kinniku Suguru) is a cowardly, clumsy, moronic, gyuudon-devouring excuse for a superhero (or Choujin)... who just happens to be the prince of an alien planet. But despite his pathetic appearance, he is very honorable and can become quite powerful when he needs to be. With his sidekick Meat-kun and fellow Choujins Terryman and Ramenman there to help him, Suguru quests to become the greatest Choujin on the planet. Whether with a combination of tremendous heart and stamina (The Burning Inner Strength) or the "Power of Friendship", Kinnikuman frequently defeats villians 10 times more powerful than him and often causes his enemies to have a change of heart and join him. Though he seems destined to be an idiot forever, slowly but surely Kinnikuman becomes worthy of the title "Hero". 
 
Notes: 
- Between volumes 36 and 37 publication there's 22 years gap. From volume 38 onwards starts restarted in 2011 version. 
- Kinnikuman won the 30th Shogakukan Manga Award for best children's manga in 1984.

Kinnikuman has proven himself worthy to be crowned the next king of Planet Kinniku. But at the ceremony, five other Kinnikuman's arrive, all claiming to be the true prince of Planet Kinniku. Now, a Royal Survivor Tournament is being held to decide the true successor to the throne, and with the help and support of his friends and with his recently acquired knowledge of the Ultimate Technique (The Muscle Spark), Kinnikuman fights for what is rightfully his.
